What is this type of bolt called?

I'm trying to buy some bolts with specific measurements. What are these types of bolts called with a smooth shank? My google foo is not working today

 

Simply just a partially threaded hex bolt, with the completely threaded bolt called fully threaded. Generally longer bolts are made this way with Fully threaded bolts being more of a specialty item

Hex head half thread bolt.

 

@My Name is Rahl , your Fastenal wisdom is needed

 

This is a partial threaded hex cap screw. You need to know shank diameter, thread pitch and length. If you take it to a hardware store or your local Fastenal, they can identify it for you and sell you it.

 

Second vote for bolt depot. They are great, fast, and reasonable.
